Well, it does technically in that to "run TypeScript" all you have to do is strip the types, and execute the remaining JavaScript. This is what Node does, but it doesn't do any typechecking. You can always include TypeScript as a dependency to do the actual type checking for you.
Deno from my understanding included a version of the TypeScript compiler as part of its build. Node doesn't do this. I'm not sure what Bun does, but I wouldn't trust it for anything more than a hobby project.
